Cartographic Bases

Accurate information about the space, for reliable decision-making, with all the necessary infrastructure and efficient planning.

Cartographic Bases

The cartographic base is the faithful representation of the physical space, in which it is possible to see the occupation, the interference in the the natural environment, the aggressions, and the eventual deterioration of the area, resulting from its growth over time and space. Knowing this physical reality is fundamental for the management of space, and the basis for convergence of knowledge of indicators of a region.

The cartographic base is representative when it has a richness of information and quality, considering that the latter concept, in cartography, depends on several parameters, such as positional quality, logical consistency, completeness, and temporal accuracy, among other aspects.

These characteristics, associated with geometric (precision), are basic conditions for the use of a cartographic base in cadastral surveys, preliminary projects, executive projects of urban infrastructure, studies on the environment, and urban planning, among other applications.

Engefoto continuously develops new solutions for obtaining high-resolution images duly accompanied by data on their geometry, in order to ensure the necessary rigidity of the resulting products.

Currently, the company has a large format digital aerial camera with 4 bands (RGB + NIR), integrated from 3 metric sensors with “matrix architecture”, each with 14204×10652, Phase One Industrial iXM-RS150F (150 MPixel each), and an Inertial Navigation System Applanix POS AV 510, called Engefoto VENTI.

This sensor produces synthetic RGBN, CIR, RGB, NIR, and NDVI images with 280 MPixels and 16 bits of radiometric resolution, with more than 20,000 orthogonal pixels to the direction of flight, with zero distortion.

The sensors used are state-of-the-art CMOS (Complementary Metal Oxide Semiconductor) of very high sensitivity and 3.76 μm of geometric resolution, as well as high-speed shutters (up to 1/2000 s), which dispense with the use of this mechanism to compensate for drag during exposure.

The first camera integrated in 2014 by Engefoto was Doppia, a sensor that was the subject of a “Case Study” of Phase One in 2016.

Engefoto was also a pioneer company in the country in the development and application of an oblique camera using two RGB sensors of 150 MPixels, a product used for imaging urban areas in Curitiba in 2019, aimed at obtaining realistic photos of the city.

Launched in 2022, Doppia 100 is a nadiral metric/oblique of medium format with 4 bands (RGB + NIR) digital camera, integrated from two Phase One Industrial iXM-100 medium format metric sensors (100 MPixel each) and one Applanix POS AV 510 Inertial Navigation System.

The assembly allows a manual adjustment of the angle of the sensors (cameras and IMU) with the nadir, ranging between 0° and 45°. It produces multispectral RGBN (4 bands) synthetic images, as well as CIR and RGB images (3 bands), NIR (1 band), Panchromatic (4 bands), NDVI and NDWI (1 band) with 100 MPixels and 8/16 bits of radiometric resolution.

The acquisition of these oblique images follows the global market trend of 3D representation of information, with full use of point cloud.
